    "abstract": "We show that a central $1/r^n$ singular potential (with $n\\geq 2$) is\nrenormalized by a one-parameter square-well counterterm; low-energy observables\nare made independent of the square-well width by adjusting the square-well\nstrength. We find a closed form expression for the renormalization-group\nevolution of the square-well counterterm.",
